Bro it’s a’c’d the sun the moon and the earth their energy works together pushing and pulling towards the earth creating a gravitational pull.
Step-by-step explanation:
Answer:
-2
Step-by-step explanation:
x = r cos θ
y = r sin θ
dx/dθ = -r sin θ + r' cos θ
dy/dθ = r cos θ + r' sin θ
dy/dx = (r cos θ + r' sin θ) / (-r sin θ + r' cos θ)
At θ = π/2, cos θ = 0, sin θ = 1, and r = 1. So the derivative simplifies to:
dy/dx = (r') / (-1)
dy/dx = -r'
dy/dx = -2 sin θ
dy/dx = -2
Answer:
He can make 2 batches of lemonade with 1 pint of lemon juice.
Step-by-step explanation:
First convert 1 pint to ounces
1 pint of lemon juice = 16 fluid ounces
To get the number of batches that can be made with 1 pint (16 fluid ounces) of lemon juice, we can simply use proportion;
Let x be the number of batches Farid can make with 1 pint(16 fluid ounces) of lemon juice
8 fluid ounces = 1 batch
16 fluid ounces = x
cross-multiply
8x = 16
Divide both-side of the equation by 8
8x/8 = 16/8
x= 2 batches.
Therefore, he can make 2 batches of lemonade with 1 pint of lemon juice.
